Room Program
Each room has a Position hint (Auto / Road-facing / Back / Side) β it steers which side of the plot the AI tries to place it on. Add a room and it regenerates immediately.
Manual editing: click any room, then drag its corner/edge handles to resize, or drag the body to move it β works immediately, no mode switch needed. Dragging a shared wall (e.g. Hall/Kitchen boundary) resizes the room on both sides together, no gaps or overlaps. DRAW ROOM adds a new rectangle by hand. SET SIZE types exact dimensions. Loads/columns/beams/footings recalculate automatically after every change.
Dead Load Build-Up (composite)
Computed Dead Load
---
Slab self-weight (thickness Γ density) + finishes + wall weight smeared over floor area, same build-up method as a typical structural calc report (exterior/interior wall kg/mΒ² are per wall-face area defaults β adjust to your actual wall buildup).

Seismic Parameters β ASCE 7-16 Ch.11/12
Wind Parameters β ASCE 7-16 Ch.26
See the Lateral tab on the right for Fa/Fv site coefficients, SDS/SD1, Seismic Design Category, base shear (equivalent lateral force method), and estimated wind pressure/force β full ASCE 7-16 modal/response-spectrum analysis (ETABS) is still required for final design.
Preliminary schematic only. Composite load build-up and ASCE 7-16 equivalent lateral force/simplified wind procedures β correct methodology, but not a substitute for full FE analysis (ETABS), slab/mat design (SAFE), retaining wall design, or sign-off by a licensed structural engineer.
